I went to the Matrox site and downloaded and installed the beta 
drivers.  Tempting fate I went ahead and enabled 3D Acceleration but 
didn't test the config, just saved it.  The screen savers now zip right 
along, but I still can't play tux racer.  When I go to run tux racer I 
get a black screen with bold red letters in the middle stating that the 
signal frequency is out of range.

Signal frequency is out of range
FH: 28 kHz  FV: 57 Hz
Please change signal timing

FWIW I checked the SuSE supported hardware site and the Matrox G450 is 
listed as fully supported.  From what I can tell the past couple of 
days, its anything but fully supported.  I wonder why it wasn't 
identified during the install?  At this point I guess I'm satisfied as I 
don't really want to play tux racer, I just wanted to use it as a rough 
gauge of how well 3D was working.
